Your officially my hero.
This... is... godly!... One of the best games to date for sure. Couple of things though...
1.It would nice to have actual numbers that show you the amount of ammo you have instead of bars...
2.It gets laggy when there is more then 2 players on the screen.
3.There are some glitches.
4.Would be even cooler with different gameplay modes and with powerups etc.
Other then that, good job!
